Bike is suddenly running at lower power. Like at 80%. As if something is causing it to struggle. Two days ago i had to park the bike in the shed before it rained so I started it with choke on, and didnt let it warm up, and rode it/coasted it into the shed and turned it off. I never run the bike until its warmed up but i was in a hurry. The next day i go to start it and the first thing i notice when i started it on full choke is how the bike was much quieter/the bike's rpm wasn't as quick as it normally is on full choke. I put the choke to half and the bike started revving a bit more faster. I put it back to full choke thinking im crazy and the bike bogged down a bit. I took the bike to work and the next thing i notice is that the bike definitely feels off and sounds off, especially in the first gear and a a bit in second gear. Less noticeable in the higher gears.
First thing i though is my carbs were out of sync. So i checked and they were still perfectly in sync. Next I check the rpm using my gauge because of how quiet the bike sounds. (Hard to explain but I'm really in tune with how my bike sounds and feels and since all this started the bike has definitely sounded much quieter than normal). So i check the rpm and its still set at 960 which floors me because i remember when i first set it to 960 how much louder and faster my idle sounded on the bike. Another thing I noticed is how hot the engine feels shortly after starting the bike. I never used to feel any engine warmth on my leg when starting and letting the bike warm up but now suddenly i notice it a lot. I haven't had the chance to take it all apart yet but i wanted to reach out to everyone to collect your thoughts so i can have a list of things to check. At the top of my head here's what I'm thinking:
-Air leak? Since putting the choke on full, is causing the bike to bog, so that tells me it's not getting enough air?
-TPS Sensor is off again? Since I just adjusted it last week when I lowered it from over 800 down to spec (700 closed throttle). Maybe the sensor is faulty and is now lower than it should be?
-Carbs are dirty again, even tho i just cleaned them a month or two ago...
-Bad fuel pump or Fuel filter?
